Magnetic outflows stemming from star mergers, analysis concludes"},"content":{"rendered":"<p> <br \/>\n<\/p>\n<p id=\"first\">Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million times what can be achieved by humans. But while the existence of UHECRs has been known for 60 years, researchers have not succeeded in formulating a satisfactory explanation for their origin that explains all the observations.<\/p>\n<div id=\"text\">\n<p>But a new theory introduced by New York University physicist Glennys Farrar provides a viable and testable explanation for how UHECRs are created.<\/p>\n<p>&#8220;After six decades of effort, the origin of the mysterious highest-energy particles in the universe may finally have been identified,&#8221; says Farrar, a Collegiate Professor of Physics and Julius Silver, Rosalind S. Silver, and Enid Silver Winslow Professor at NYU. &#8220;This insight gives a new tool for understanding the most cataclysmic events of the universe: two neutron stars merging to form a black hole, which is the process responsible for the creation of many precious or exotic elements, including gold, platinum, uranium, iodine, and xenon.&#8221;<\/p>\n<p>The work, which appears in the journal<em> Physical Review Letters<\/em>, proposes that UHECRs are accelerated in the turbulent magnetic outflows of Binary Neutron Star mergers &#8212; spewed out from the merger remnant, prior to formation of the final black hole. The process simultaneously generates powerful gravitational waves &#8212; some already detected by scientists at the LIGO-Virgo collaboration.<\/p>\n<p>Farrar&#8217;s <em>Physical Review Letters<\/em> proposal explains, for the first time, two of the most mysterious features of UHECRs: the tight correlation between a UHECR&#8217;s energy and its electric charge and the extraordinary energy of a handful of the very highest energy events.<\/p>\n<p>Stemming from Farrar&#8217;s analysis are two consequences that can provide experimental validation in future work:<\/p>\n<ul>\n<li>The very highest energy UHECRs originate as rare &#8220;r-process&#8221; elements, such as xenon and tellurium, motivating a search for such a component in the UHECR data.<\/li>\n<li>Extremely high-energy neutrinos, originating from UHECR collisions, are necessarily accompanied by the gravitational wave produced in the parent neutron star merger.<\/li>\n<\/ul>\n<p>The research was supported, in part, by grants from the National Science Foundation (PHY-2013199, PHY-2413153).<\/p>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.sciencedaily.com\/releases\/2025\/02\/250228214821.htm\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million times what can be achieved by humans.<\/p>\n","protected":false},"author":1,"featured_media":91671,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[173],"tags":[],"class_list":["post-91670","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-science"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/posts\/91670","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/comments?post=91670"}],"version-history":[{"count":0,"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/posts\/91670\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/media\/91671"}],"wp:attachment":[{"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/media?parent=91670"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/categories?post=91670"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/neclink.com\/index.php\/wp-json\/wp\/v2\/tags?post=91670"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
